Wipe cache partition on your Android smartphone (data is not deleted!)
Turn your Android smartphone off by long pressing on the Power On / Off button. Now you need to press and hold the following key combination:
- Power On / Off
- Volume +
- Home button
If your phone vibrates once, release the Power On / Off button, but keep the other two keys from the key combination pressed until a menu appears on the display. Here you can now use the volume button to select "Wipe Cache Partition". Confirm with the "Power On / Off" button to delete the cache. Then mark "Reboot phone" to reboot your Android phone. Finish!
Then, the error "Unfortunately the process com.android.phone has stopped" should no longer appear when you open an app like the phone app....
